After a rough several weeks, things are looking up for Jen Arnold.The Little Couple star revealed on Tuesday that her rare form of cancer is in remission.

“It’s official- ME 1 vs CANCER 0… I WIN! Thank you for all the prayers, thoughts, & support!” she tweeted. The mom of two finished her final chemo treatment, and said “everything is moving in the right direction.”

Jen’s stage 3 choriocarcinoma occurred after a failed pregnancy. She announced the diagnosis in December, just weeks after she and husband, Bill Klein, adopted their second child. Her struggle with the disease was documented and is expected to play out on TLC, the network which has been documenting the couple’s story since 2009.

“What a wonderful way to celebrate #WorldCancerDay! I am done with cancer!” the reality star added. “Thank you to all who supported #GetWellJen– DONE! I am getting well!!!”
